Title: Managing make-up gas composition variation for a high pressure expander process
Inventor: LIU YIJUN
IPC: F25J1/00
Filed: 2019-07-30
Granted: 2023-04-13
Abstract: A method for liquefying a feed gas stream. A refrigerant stream is cooled and expanded to produce an expanded, cooled refrigerant stream. Part or all of the expanded, cooled refrigerant stream is mixed with a make-up refrigerant stream in a separator, thereby condensing heavy hydrocarbon components from the make-up refrigerant stream and forming a gaseous expanded, cooled refrigerant stream. The gaseous expanded, cooled refrigerant stream passes through a heat exchanger zone to form a warm refrigerant stream. The feed gas stream is passed through the heat exchanger zone to cool at least part of the feed gas stream by indirect heat exchange with the expanded, cooled refrigerant stream, thereby forming a liquefied gas stream. The warm refrigerant stream is compressed to produce the compressed refrigerant stream.

Title: Loading station for automatically loading to and from the long sides of standardised transport receptacles
Inventor: MIEBACH ERNST DIPL-KFM DR JUR
IPC: B65G63/02
Filed: 1984-06-09
Granted: 1985-12-05
Abstract: Loading station for automatically loading a plurality of transport units at a time to and from the long sides of standardised transport receptacles, after the transport units have been fed by all the conventional conveying systems or by forklift trucks onto an automatically laterally travelling transfer platform, and have subsequently been picked up by a driverless loading vehicle during an interruption in material flow, for use by large despatchers (also goods distribution centres) and small or medium-sized enterprises. The transport units are deposited one behind the other on the transfer platform. The latter is, so to speak, the "mother vehicle" on and by means of which the loading vehicle, as the "daughter vehicle", is moved parallel to the longitudinal sides of the transport receptacles into the correct position for loading, accepts the transport units there and moves them into and deposits them in the transport receptacle perpendicularly to the direction of travel of the displacement platform, and vice versa. The drive carriage of the loading vehicle does not enter the transport receptacle. The travelling elements of the displacement platform have been provided in such a way that passageways, which hinder transverse traffic, can be dispensed with on the ramp.

Title: Chuck
Inventor: FRIEDRICH LINK HELMUT
IPC: B23B31/175
Filed: 1984-12-29
Granted: 1986-06-19
Abstract: The invention relates to a chuck in which the chuck jaws are connected to the chuck body via radially deflectable webs, preferably two flat, parallel webs being provided per chuck jaw, which webs act like leaf springs and provide for parallelogram guidance of the allocated chuck jaw. The chuck jaws and webs are preferably formed in one piece with the chuck body by slots being produced in corresponding projections of the same by means of electrical discharge-wire cutting. According to the invention, the chuck jaws are actuated via a wedge-surface arrangement with a double-armed lever per chuck jaw, a short arm of the lever acting on the allocated chuck jaw, while a wedge surface on a distinctly longer arm of the lever interacts with an actuating element, in particular a roller, of an axially movable actuator.

Title: Equipment to measure the opening pressure of twin-spring nozzle holders having pintle-type nozzles
IPC: F02M65/00
Filed: 1988-07-20
Granted: 1989-11-09
Abstract: The equipment to measure the opening pressure of twin-spring nozzle holders has a housing (20) in which the nozzle holder is firmly arranged. By means of the force of a spring (21), a pressure pin (22) is pressed against the pintle (18) of the nozzle needle. When loaded with pressure means, the nozzle needle carries out a lifting movement, which the pressure pin (22) follows exactly. The latter is operatively connected to a distance transmitter (24), an electrical signal being generated by means of the alteration of the electrical resistance across a measuring bridge, as a function of the movement of the pressure pin. This gives information about the first and second opening pressure. <IMAGE>

Granted: 1992-12-17
Abstract: The soles have a bottom sole, an upper sole and an inner sole connecting the bottom sole to the upper sole. In a first process step the bottom sole and the upper sole are moulded using two side mould parts (11), a shell-type, i.e. recessed cavity, bottom die (1), a last (17) carrying a shoe upper which is placed on the side mould parts in the closed position, and an insertable contour plate (2, 6, 8) dividing the space between the side mould parts into two mould cavities (15, 16), respectively for the bottom and upper soles.

Title: Method and arrangement for outputting digital speech signals
Inventor: CLUEVER KAI DIPL ING
IPC: H04L12/64
Filed: 1993-07-28
Granted: 1994-08-25
Abstract: Upon receiving a valid message packet following a transmission in a communications network in accordance with the asynchronous transfer mode (ATM), a predictive analysis of the incoming speech signal (x(n)) is undertaken for calculating filter coefficients (e(i), a(i)) for a digital input filter (PF) and for a digital output filter (SF). A difference signal (d(n)) is formed from the incoming speech signal (x(n)) from the input filter (PF) and is fed to the output filter (SF) as excitation signal (e(n)). The input filter (PF) and the output filter (SF) have transfer functions inverse to each other, so that the speech signal (y(n)) is formed and output by the output filter (SF), as a function of the calculated filter coefficients (e(i), a(i)). Apart from the predictive analysis of the incoming speech signal (x(n)), an analysis is undertaken of the excitation signal (e(n)), for determining a period (M) of the speech signal basic frequency, using which, whilst maintaining the filter coefficients (a(i)), a substitute signal (e(n-M)) is formed by means of base-frequency-synchronous repetition of the excitation signal (e(n)) in the case of the last-received message packet. Upon losing a message packet, the substitute signal (e(n-M)) is fed as output signal (e(n)) to the output filter (SF), which forms and outputs a substituted speech signal (y*(n)). <IMAGE>
